Twin Air Fuel Filter KTM SX-F 250/350/450 11-12,EXC 250-500

You’d be amazed at the dirt and debris that can work its way into your gas can – and from there, into your fuel tank.

Twin Air’s monofilament screen pocket inserts in your tank to catch particles as small as 40 microns (.00165”) while allowing the gas to flow freely.
The flange is custom-sized for each modern 4-stroke model to ensure a leak-proof seal.

Just remove the filter periodically, turn it inside-out, and clean out the debris that COULD have been in your engine.
